PRODUCT DESCRIPTION

Two-Type Compatibility (USB-C & USB-A 3.0)

With the UGREEN CM304 (80191), you can avoid carrying separate adapters since it sports not only a USB Type-C male connector at one end but also a standard USB Type-A 3.0 male connector at the other end. Thus, in this two-ended pen-drive format, you can easily connect to USB-C-enabled mobile devices, Android tablets, iPad Pros, and Thunderbolt-enabled MacBooks at one end, and traditional USB-A devices at the other end.

Concurrent Read/Write to Dual Slots at 5Gbps Transfer Rate

While ordinary card readers require the removal of the SD card before accessing the microSD card, the CM304 comes equipped with a highly efficient Genesys Logic GL3224 master controller chip, which enables reading and writing to both the SD slot and TF (MicroSD) slot at once. Working under the USB 3.0 (USB 3.1 Gen 1) transfer protocol at up to 5 Gbps, it reads gigabytes of 4K drone footage, RAW photo bursts, and high-bitrate videos from SD cards at 100MB/s.

On-the-Go (OTG) Workflow of the Mobile Phone and 2TB Capacity

Thanks to the built-in USB OTG (On-The-Go) capabilities, the creator can extract a microSD card from the action camera or the drone and simply plug the card reader into the USB-C phone, and then instantly view, edit, and/or distribute HD content without the need for a PC. This card reader is tested and certified with high-capacity memory cards up to 512GB, and its architecture allows for cards up to 2TB.

Durability & Safety Features of the Compact Design

With a length of only 73 mm and a weight of around 20 grams, the CM304 comes in a matte-finish ABS material with anti-impact protection. The device has dust caps on either end to protect its metal USB pins from getting dirty or damaged by loose threads in the pocket. Inside the unit, there are safety fuses to protect from short circuits and ESD discharge.
